The questions where ChatGPT currently names GitBook.
The best knowledge base software depends on whether you're building an internal company wiki, a customer help center, or technical/developer documentation.
Here's a practical shortlist:
| Tool | Best for | Strengths | Considerations |
|---|---|---|---|
| Notion | Internal knowledge | Easy to use, databases, AI, collaboration | Public documentation isn't its strongest feature |
| Confluence | Engineering & large teams | Deep integrations with Jira, permissions, versioning | Can feel complex for smaller teams |
| Document360 | Customer-facing knowledge bases | Excellent search, analytics, AI writing, multilingual support | Higher cost than wiki-style tools |
| Zendesk Guide | Support teams | Tight integration with Zendesk tickets and AI | Best if you already use Zendesk |
| Help Scout Docs | Small support teams | Clean UI, simple setup, integrated with Help Scout | Fewer advanced customization options |
| GitBook | Developer documentation | Beautiful docs, Markdown, Git integration | Geared toward technical audiences |
| Guru | Sales & operations teams | Browser extension, AI answers, Slack integration | Less suited for public documentation |
| Slite | SMB internal documentation | Modern interface, collaborative editing | Smaller ecosystem than Notion or Confluence |
Recent industry comparisons consistently rank Notion, Confluence, Document360, GitBook, and Help Scout among the strongest options, with the best choice depending on your use case rather than one overall winner. front.com
